I have done the ToS the last few years and have always enjoyed it.
I am in two minds this year
a) because I am in mid TR plan
b) They have added yoga and strength workouts to it which seems to detract a little in my mind.
It is normally a very hard 10 days - 700-900 TSS if done at 100% which is what I aim for and does take some recovery. However the FB thredas are great and generate a real community spirit.
I will be on the last week of SSBase MV Pt 2 which is a recovery week. Not sure I want to not finish the plan properly before I start on a build plan.
Anybody else doing it.
